Why and which type of tertiary winding is used in most of the power transformer?..

Answer / iamdon

The primary and secondary windings are used for normal
voltage/current transformation where as the tertiary
winding is used for following special purposes

1)Supply to substation auxiliaries.
2)Connecting static capacitors/synchronous condenser etc

The tertiary winding is connected in delta to allow the
flow of zero sequence current in the tertiary loop in the
case of unbalance.
